Optical spectrum of the sun
WebNov 14, 2014 · Infrared and optical astronomers generally use wavelength. Infrared astronomers use microns (millionths of a meter) for wavelengths, so their part of the EM spectrum falls in the range of 1 to 100 microns. … WebOur Sun produces more yellow light than any other color because its surface temperature is 5,500°C. If the Sun's surface were cooler—say 3,000°C—it would look reddish, like the star Betelgeuse. If the Sun were hotter—say, …

WebJul 17, 2015 · The visible spectrum covers wavelengths of roughly 390 nanometers to 780 nanometers (astronomers often use units of Angstroms (10-10), so visible light spans 3,900 to 7,800 Angstroms). WebThe spectral energy distribution of solar light has a maxima in the visible portion.This is at around 1.5 eV and hence the semiconductor having band gap near 1.5 eV is preferred for solar cells....
WebUltraviolet ( UV) radiation is the highest-energy form of optical radiation and includes the wavelengths from 100 to 400 nanometres ( nm ). The term "visible light" refers to the region of the electromagnetic spectrum that humans can see. These wavelengths range from 400 to 780 nm. Some animals can see a wider region of the spectrum than humans. WebMar 9, 2007 · The spectrum of the Sun as seen with our cereal-box spectrometer. The lines correspond to: (1) hydrogen at 656 nm, (2) sodium at 589 nm, (3) iron at 527 nm, (4) magnesium at 518 nm, (5) hydrogen at 486 nm, and (6) iron and calcium at 431 nm.
